基于LabVIEW的测试系统误差分析
Analysis of Error in Test System Based on LabVIEW
【摘要】 建立两种数据模型:基于LabVIEW平台的参数测试系统观测数据模型和理想数据模型。以此模型为基础,分析数据中的系统误差和研究系统误差的检验方法,提出了基于后验检验统计的系统误差检测法。讨论了随机误差的分布、测度。最后修改观测数据的模型,结合此模型研究系统误差和随机误差的评定指标。
【Abstract】 In test systems,the test error will affect the accuracy of the data.It is crucial to weaken the effect of errors on the test results.Two data models are built up,namely the test data model based on LabVIEW and the ideal data model.Then the systematic error in test data are analyzed,and the method for the error inspec- tion is studied.The detection method for systematic errors based on the posterior testing statistics is put for- ward.The distribution and the measure of the random error are analyzed.Finally,the assessment indicators of the systematic error and the random error are discussed with revised data model.
【Key words】 testing system; data model; random error; evaluation index;
